Wireless vehicular communications possess significant challenges for their massive deployment in next generation vehicular networks. Some important issues that must be tackled deal with security, billing and scalability in order to provide reliable services in the case of non-safety applications. In this paper, the authors study a service provisioning protocol intended for Vehicular-To-Infrastructure (V2I) environments where service access is granted by administrative areas in the form of service district domains. To provide scalability of the service, it is necessary to share the current user service parameters between active district domains. Their analysis covers the average response time for requesting on-demand services as well as for sharing service parameters between district domains.
